2 posts ago, I used Napster as an example of my main beef with DRM: when the provider can't (or won't) authenticate your access anymore, you lose the content and thus you're renting it instead of buying it.
I just got an email from Napster's support team with instructions on how to fix the problem and who to contact if it doesn't work out.
What's amazing is that the previous entry was the only place I'd mentioned the problem... I hadn't created a ticket or anything because I wasn't really concerned with recovering the music. They just found the post, figured out my account and the tracks, setup a ticket, and sent me instructions. Within 2 days.
That's some pretty fscking impressive customer service, fellahs. :)
